Udomitelj potpisuje ugovor o udomljavanju.

Udomitelj is the person who takes someone into foster care or provides foster placement. In English, depending on context, it can be translated as foster parent, foster carer, or sometimes caregiver.

A few useful related forms:

• udomitelj = male foster carer / generic singular
• udomiteljica = female foster carer
• udomiti / udomljavati = to place into a home, to foster, sometimes to rehome

So in this sentence, udomitelj is the person doing the signing.

Croatian does not have articles like English the and a/an.

So udomitelj can mean:

• a foster carer
• the foster carer

and ugovor can mean:

• a contract
• the contract

Which one sounds best depends on context. Croatian leaves that to the situation instead of using articles.

Potpisuje is:

• 3rd person singular
• present tense
• from the verb potpisivati = to be signing / to sign repeatedly or habitually

So it matches the subject udomitelj = the foster carer signs / is signing.

In Croatian, present tense can often translate in more than one way in English:

• signs
• is signing

The exact English version depends on context.

This is a question about aspect, which is very important in Croatian.

• potpisivati → imperfective
• potpisati → perfective

Their present forms are different:

• potpisuje = imperfective
• potpiše = perfective form, but in many contexts this present form refers to a future completed action

In a neutral statement like a rule, procedure, or general description, Croatian often uses the imperfective:

• Udomitelj potpisuje ugovor... = The foster carer signs the contract / signs a contract

If you used potpiše, it would usually sound more like:

• when he/she signs
• he/she will sign

So potpisuje is the natural choice for a general statement.

Because ugovor is a masculine inanimate noun, and in the singular its:

• nominative = ugovor
• accusative = ugovor

Here it is the direct object of potpisuje, so it is in the accusative, but it happens to look exactly the same as the nominative.

That is very common with masculine inanimate nouns in Croatian.

Udomljavanju is in the locative singular.

It is used because of the preposition o, which in this meaning takes the locative:

• o + locative = about, concerning

So:

• ugovor o udomljavanju = a contract about fostering / a fostering contract

This is a very common Croatian pattern:

• knjiga o povijesti = a book about history
• razgovor o poslu = a conversation about work
• ugovor o radu = employment contract

The basic form is udomljavanje.

That is a verbal noun, roughly meaning:

• fostering
• placement into a home
• sometimes rehoming, depending on context

The case change is:

• nominative: udomljavanje
• locative: o udomljavanju

So the ending changes because it follows o.

Not necessarily.

Udomljavanje usually refers to fostering, placement into care, or rehoming, depending on context. It is often not the same as full legal adoption.

A learner should be careful not to assume it always means the English adoption.

Related terms:

• udomljavanje = fostering / rehoming / placement into a home
• posvojenje or usvojenje = adoption

The exact best translation depends on whether the context is social care, children, or animals.

Yes. Croatian word order is more flexible than English because cases show the grammatical relationships.

The neutral order here is:

• Udomitelj potpisuje ugovor o udomljavanju.

But other orders are possible, for example:

• Ugovor o udomljavanju potpisuje udomitelj.

That version puts more focus on the contract.

Even though the order can change, the most natural order depends on what you want to emphasize.

Grammatically, udomitelj is a masculine noun. It can refer to:

• a male foster carer
• or a person in a general, role-based sense

If you want to refer specifically to a woman, you would normally say:

• udomiteljica

So the sentence could become:

• Udomiteljica potpisuje ugovor o udomljavanju.

A rough pronunciation guide is:

Udomitelj potpisuje ugovor o udomljavanju
oo-doh-MEE-tyelh poht-pee-SOO-yeh OO-goh-vohr oh oo-dohm-lya-VA-nyoo

A few pronunciation notes:

• lj is a single sound, similar to the lli in some pronunciations of million
• j is pronounced like English y
• stress is not usually marked in normal writing, so learners usually pick it up from listening

The trickiest part for many English speakers is udomljavanju, especially the mlj cluster.
